The Earth Kingdom is the largest and most populous country in the known world, and encompasses the overwhelming majority of Earth Nation polities. Its inhabitants are primarily of Earth National elemental ethnicities and hence its culture and history have been heavily influenced by the development of Earthbending.

The Earth Kingdom is vast and diverse, with 51 provinces and four constituent states. It controlled substantially all of its claimed territory at the start of the Fire Nation invasion, but now some provinces are controlled by the Fire Nation colonial government and others have attained de facto independence after neglect or perceived abuse from the Ba Sing Se government.

The Earth Kingdom is divided into nine regions, eight of which have regional capitals and the other of which is coterminous with the outer barrier wall of the royal capital, Ba Sing Se.

Many of the political subdivisions of the Earth Kingdom have histories as independent countries that were tributaries of the Central Earth Kingdom government in Ba Sing Se, and which were later incorporated as organic parts of the kingdom. Four of these subdivisions, originating as vassal kingdoms, are termed states rather than provinces, with leaders who are "prince" or "king / sovereign" (王), the latter term also being used for the Earth Monarch in Ba Sing Se. For historical reasons, many of the provinces are still called countries (國) even though their leaders are not allowed to call themselves kings/princes (or queens/princesses.) The Earth Monarch is usually an Earth King (土王), though sometimes there have been Earth Queens regnant who use the same title as when the Earth Monarch is male, and under the Great Ri the Earth Monarch was titled Emperor of the Great Ri in most contexts, being called "Earth King" only in the context of his rule in Ba Sing Se.

Geography

The Earth Kingdom is enormous and contains essentially every biome from frozen glaciers to torrid jungles.

Ethnic Groups

The Earth Kingdom has forty-one widely-recognized Ethnic Groups, many of which contain subdivisions. The term "Earth Peoples" (土民) is collectively used for everyone who isn't descended from the natives of Ba Sing Se. Ba Sing Se natives (the ancestral stock of both the Hao and the Ting) are not considered "ethnic" by the Hao Ting, though the Ri and Later Gong used the term Guchengminzu (固城民族) "Solid walls ethnic group" for them. The Guchengminzu may be considered the "zeroth" group on the list below, although they are not on the official lists.

Monarchy and Symbolism

See Dynastic History of the Earth Kingdom for the historical development and key points of the history of the monarchy.

The Earth Kingdom is ruled by the Earth King, who reigns from the Badgermole Throne in the Hall of Invincible Stability, part of the innermost palace complex in Ba Sing Se. Earth Monarchs assume rulership by "ascending the throne" and issuing an edict stating this fact and proclaiming an Era Name to be used on the new year. (Thus, an Earth King first rules during the last year of the era of his predecessor; interregnums are normally very short unless the former Earth King has died close to the new year, in which case the official ascension would be delayed lest confusion about the current era name be created in the far-flung corners of the Kingdom.)

Iconography of the monarchy varied by dynasty. The current Hao Ting favors a circular symbol with a central square hole, somewhat resembling a cash coin. The preceding Ri dynasty used a stylized badgermole and a quadripartite symbol similar to the yin-yang (࿌). The Hao dynasty immediately preceding the Ri also used badgermole symbolism; the austere Ting used a circular symbol more similar to the current emblem until the recovery of the ancient badgermole throne.

Green is the national color of the Earth Kingdom. Traditionally, the color of the Earth Monarch's regalia was described as "celadon," though the current regalia no longer closely fit that color description.

Military

The Royal Earth Army is the traditional army of the Earth Kingdom. It has a proud and storied history, but as of 95 AG the organization has fallen on hard times. Most of the best units have been decimated in battle with the Fire Nation; many of the remaining troops of the regular army are tied up in ensuring the flow of taxes to Ba Sing Se or protecting the outer wall. The defense of the West and South has largely been left to highly-autonomous provincial generals, warlords in all but name, who levy their own taxes and conscript local people on their own authority. They fight the Fire Nation invasion, bandits, rebels (such as those who refuse to give them money or soldiers), and occasionally, each other. These generals act in a poorly-coordinated fashion, often preferring to defend their local bases of support rather than pursue objectives in the interest of the Kingdom overall; they treat orders from Ba Sing Se as more of suggestions which they might implement or not. Lately, the Hao-Ting war council has come to accept that it has to bribe them to do anything against their self-interest. The warlord armies are usually controlled with brutal discipline, but that does not extend to their treatment of defeated enemies, as they often engage in war crimes. That being said, some of the warlord generals are comparatively chivalrous; the legendary scholar-general YANG Guofan and his Gaoling Army are both loyal to the state and well-disciplined.

The Earth Navy uses mainly sailing ships. It was decimated by the Fire Nation early in the course of the war, as they were no match for the metal-hulled and steam-propelled Fire Navy. The Earth Navy in the far East and Outward Lands has experimented with a few steam-powered ships of their own, based on captured Fire Nation technology, but without firebending, both the operation and building of such ships is limited. (Notably, they are still wooden steamships, except for a couple of Fire Nation ships that ran around and were captured.) Most of the Earth Navy's large sailing ships are in the sea between the mainland and the outlying Southern territories of the Earth Kingdom; the experimental steamships and captured Fire Nation ships are kept in the Eastern Sea to defend Ba Sing Se from an attack from the East. (The strategic merits of this decision are questionable.) With the assistance of Southern Water Tribe members who joined the war, the Earth Kingdom does conduct some commerce raiding with smaller vessels against Fire Nation shipping between the Fire Islands and their colonies in the Earth Kingdom. However, as the Fire Nation has started modernizing their merchant navy and started to use convoy escorts, these raids have become less effective.
